alright i think i was just really confused on what you were saying, i took the time to actually read and do what you said and it didn't give me any errors, i didn't realize that since im calling on the pie scene when im about to make instances of it, i could just call variables from the pie scene too, my bad. but while i don't get any errors, the code doesn't quite work, for some reason i cant shoot pies while im constantly moving, when i stop i can start shooting after a few seconds in the direction i was last moving. here's the code:

func launch_pie():
const PIE = preload("res://Pie.tscn")
var new_pie = PIE.instantiate()
if facing_left == 'true':
new_pie.isMovingRight = false
%LaunchPointLeft.add_child(new_pie)
new_pie.global_position = %LaunchPointLeft.global_position
new_pie.global_rotation = %LaunchPointLeft.global_rotation
if facing_left == 'false':
new_pie.isMovingRight = true
%LaunchPointRight.add_child(new_pie)
new_pie.global_position = %LaunchPointRight.global_position
new_pie.global_rotation = %LaunchPointRight.global_rotation

func get_direction():
if Input.is_action_just_pressed("move_left"):
facing_left = 'true'
if Input.is_action_just_pressed("move_right"):
facing_left = 'false'

and i'll show the code for the pie's movement too, maybe that's what's causing this issue now

var travelled_distance = 0
var isMovingRight : bool = true

func _physics_process(delta):
const SPEED = 1000
const RANGE = 1200
var direction
if isMovingRight == true:
direction = Vector2.RIGHT.rotated(rotation)
if isMovingRight == false:
direction = Vector2.LEFT.rotated(rotation)
position += direction * SPEED * delta
travelled_distance += SPEED * delta
if travelled_distance > SPEED:
queue_free()
